6.5:1 Rail Auto Zoom Lens
The rail-type automatic zoom lens has changed the traditional curved motion mode of the lens and adopts a high-precision and high-efficiency linear rail motion system with smaller friction coefficient. The internal optical grating real-time records the position of the two sets of optical lenses moving up and down, which eliminates the optical effects and various frictions that cannot be avoided in traditional zoom lenses. This greatly improves the optical performance, precision, stability, and service life of the lens.
